1st December 2017: Russian forces enter Estonia, Finland and Poland, taking NATO by surprise. Resistance in all three countries is stiff, and US, UK, French, German and Italian aircraft all provide air support.

In the Dail, the Irish government condemns the invasion. Fianna Fail and Sinn Fein call for the United Nations “to act”. They are not specific on detail.

2nd December: it is now clear that a full Russian invasion is underway. Media briefings in Moscow clarify that the purpose of the “pre-emptive defensive action” is to secure the Baltic states, Poland and Finland as neutral states outside of NATO. President Putin goes on TV to explain the action, and, speaking in fluent German, pledges that only those countries are combat areas, and that Russian forces will not invade other European countries.
